osx - Permission issue on some files on a NAS D-link DNS 325

    I have some permission issue with folders on my NAS, and I have no idea how to get the reset permission for these files. I'm having a D-link DNS-325.

    My volume is mounted using afp, connected with a user I set in the panel admin of the NAS.

    I'm working on Mac, I tried many things and I always get the message "The operation can’t be completed because you don’t have the necessary permission."

    enter image description here

    Although I can access those files using the "Web File Server" to explore my file from the panel admin. Do you have any idea how I can restore my permission?

    I have my user folder on a another (internal) disk. Now I have to repair permissions and don’t know how to do it. I suppose to do this via the terminal would be the proper way.

    If there is any tool, app or way to do this please enlighten me.

    EDIT:

    I’ve to repair permissions because I can’t make change in the user, I can create folders and stuff like usual but if I try to change something in the system preferences, f.eg. background image, secondary mouseclick or mobileme sync the system won’t save the changes. I’ve added some details to my original question what I've tried so far.

    HERE is a screenshot of my information dialog which visualizes how my permissions are set up. (Sorry - as a new user I couldn’t post an image, so the link will have to do.)

    Since Steve Folly suggested to change the permissions on the ownership I tried that and typed this into the terminal:

    sudo chown -R patte:patte /Volumes/Lagerhalle\ 1/patte

    But sadly got Invalid argument back in return. Desperadly I also tried some variations:

    sudo chown -R username:patte /Volumes/Lagerhalle\ 1/patte
sudo chown -R admin:admin /Volumes/Lagerhalle\ 1/patte

    Same response from terminal: Invalid argument.

    I also did the other suggestion / the following step:

    sudo chmod -R 755 /Volumes/Lagerhalle\ 1/patte

    It went alright but in two little Dropbox folders it told me Operation not permitted - so these 2 folder are no big deal.

    sidenote: you can see that the drive is named "Lagerhalle 1" since I recently had to backup and rebuild the drive. Since the clone was also named "Lagerhalle" the rebuild partition was automatically named "Lagerhalle 1". I tried to rename the partition to the name without the "_1" by erasing the backup volume and renaming it via terminal but the "_1" still remained. But that's another story….

    PS: What I was wondering about is if it's correct that there is no admin on my 2nd HD. I had it all working once, but couldn’t recall if it was always that way (that the admin is only on the root volume/system volume).

    I have to ask - how do you know you have to repair permissions?

    Disk Utility's 'Repair Permissions' feature is for repairing permissions on installed applications and system features typically on the start up disk. As you seem to have realised, it doesn't touch user folders.

    Do you have file ownership problems - i.e. files in the user's folders are not owned by them? Or permission problems - i.e. other users can read too many files?

    chmod and chown are probably your best bet from the command line.

    $ sudo chown -R username:username /path/to/username

    Once you've set the ownership correctly, your should be able to chmod your own files:

    $ chmod -R 755 /path/to/username

    Solution

    This is what helped me out:

    $ sudo chmod -R ug+rwX /path-to-username/shortname
